PLOW.

SPECIFICATION forming part of Letters Patent No. 491,599, dated February14, 1893.

Application filed April 9,1892. Serial No. 428,488. (No model.)

To aZZ whom t may concern:

Be it known that I, HENRY G. SCHMITT, of Hendy Creek, in the county ofChemung and State of New York, have invented certain new and usefulImprovements in Plows; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same.

The invention relates to what are known as side hill plows, though it isadapted and intended to run on level ground, and its object is toincrease simplicity of construction, strength, efficiency of operationand ease of manipulation in plows of this class.

The invention consists in the construction hereinafter described andparticularly pointed out.

In the accompanying drawings: Figure 1 is a side elevation. Fig. 2 is aplan. Fig. 3 is a plan of a detail and Fig. 4 is a bottom plan ofmoldboard braces.

Numeral 1 indicates the beam of a plow, 2 the handles, 3 the standard, 44.- the mold boards, 5, 5 the plow points and 6 the landside or standardfoot. The mold boards are relatively arranged and joined by plates 7 and8 bolted thereto as indicated in the drawings. They are further tiedtogether and braced by the bent bars 9 and 10 and the central part ofthe latter is connected to the upper end of eachl mold board by braces11 which cross each other and are fastened together at 12. These braces9 and 10 which are shown in full lines in Fig. It, and in Fig. 1 partlyin full and partly in dotted lines are provided with eX- tensions 13through which passes the hinge pintle 14C. Corresponding extensions orlugs 15 attached to or preferably formed with the standard also receivethe pintle and together with the other parts named constitute a hingeconnection between the double mold board and the inclined rear edge ofthe standard. 16 indicates recesses in the standard adapted to receivethe lugs or extensions 13.

17 indicates slots formed one in each of two lateral extensions 17 ofthe brace 10. The double mold board turns on its hinge and permits oneor the other of these extensions to enter a slot 13 formed in thestandard. At such time the mold board fits the standard and the verticalpart of the plow point Its the notch 20 formed in the landside orstandard foot. They are locked in such position by means of two pivotedlevers 2l and 22 pivotally connected by a rod 23, and all situated inthe hollow interior of the landside, the construction and arrangementbeing such that when the free end of lever 22 is raised the free end oflever 2l will also be raised and will enter a slot 17in the brace 10, ifin proper l position, thus locking the mold board against the landside,the unlocking being effected by a reverse movement of the levers.

Lever 21 pivoted at the rear of the landside can be suitably raised tolock the plow by pressing the foot against the underside of the leverwhich may be conveniently done when the heel is on the ground. It canalso be conveniently reversed by the foot.

The handles are made adjustable in order to throw them over the centerof gravity by means of a pivot 24 adapted to' turn in a bracket or arm25, formed on or secured to the standard.

26 is a plate provided with a shoe 27, having an extension or footprovided with stops 28. Shown in Fig. 3. The edge of the foot 26 of saidplate is adapted to move back and forth llaterally in the slot or spaceprovided between a lug 29 and bracket. 25. (See Fig. 1.) The extent ofthe lateral movement iu each direction is limited by one of the stops2S. The handles each has its foot in the shoe 27 made fast to plate 26which latter is further secured to the handles by bolts 29 thrown to theright or left according to the position of the double mold board, andare secured in operative position over, or nearly over, the center ofgravity by a hook 30' which has the proper length to engage theconnecting bar 7 at its junction with the mold board. Thus when the moldboard and handles are both moved to their extreme position on the sameside, the hook will just catch over and hold the brace at its nearestend and at such time the adjacent stop 2S prevents further movement ofthe plate 26 and the handles secured thereto. Upon the top of thestandard is secured integrally or otherwise a beam pillow or beamsupporting plate 31.

32 and 33 indicate screw bolts whereby the beam is fastened to theplate.

ICO

35 Y plow beam, the beam prllow 31 having anfup'r essential.

34 and 35 indicate straps adapted to protect Ythe wood from wear by thebolts.`

7 is a slot in the standard to permit the securing in position of bolt33, and nut 36.

37 denotes a handle secured to the beam. The plate 31 is slotted at 38(see dotted lines Fig. 2) to permit the rear of the beam to be movedabout bolt 32. This operation is effected by the handle 37 which extendsup within easy reach of the plowman.

39 indicates a catch and 40 notches adapted to receive ysaid catch. rihehandle may be made sufciently elasticV to provide for the disengagementof the catch Ywhen the beam is adjusted by its means, and also to insureits return to a notch when released. The particular form of spring catchis not however `The object of the device just described is to providefor the adjusting of the angle of the line of draft to the mold boardand its point, whereby the width of the furrow may be varied.

Having thus described my invention, what I claim is:

1. In a double mold board plow, the plate 26 pivotally supported on thestandard and provided with stops 28, said stops being adapted to engagethe standard and said plate being movable independently of the beam, andthe handles fast on said plate combined with devices for looking them indifferent positions with respect to said standard and beam, consistingof a hook 30 and connecting bar 7 substantially as set forth.

2. In combination the laterally adjustable turned end provided withnotches 40 and the spring lever handle 37 provided with a catch 39adapted to be engaged with any one of said notches, said handle beingadapted to move the plow beam independently of the plow handles and tooperate the catch; substantially as set forth.`

3. In combination the laterally adjustable plow beam, the standardhaving notch 37 to give access to nut 36 on bolt 33, the beam pillow 31having an upturned end provided with notches 40 and the spring leverhandle 37 provided with a catch 39 adapted to be engaged with any one ofsaid notches whereby the beam can be moved and locked; substantially asset forth.

4. The double mold board having parts connected by the plates7 and 8,and by bars or braces 9 and 10 adapted to receive the hinge pintle,brace 10 being further connected to each mold board by a brace 11extending from near themiddleof said brace 10 to near the upper joinedends of two plow boards; substantially as set forth.

5. In combination the double mold board having its parts connected bybent bars 9 and 10, said bars being provided with lugs or hingeextensions to receive a pintle in combination with the standard havingsimilar lugs or extensions and provided with slots to receive the barlugs, and the hinge pintle, the upper joined ends of the double moldboard being connected by braces 11 with brace 10 near its hinge;substantially as set forth. j

6. The combination of the standard having a slot 18, the landside, thehinged double mold board having bar 10 provided with slots 17 and alocking device adapted to enter either slot 17 and lock the mold boardagainst the standard; substantiallyv as set forth. Y

7. The combination of the standard having a slot -18 the landside, thehinged double mold board having bar 10 provided with slots 17 and alocking device adapted to enter either slot 17 and lock the mold boardagainst the standard, said device consisting of the two pivoted bars andconnecting rod; substantially as set forth.

8. The combination of the standard having a slot 18 the landside, thehinged double mold board having bar 10 provided with slots 17 VandV aYlockingdevicefadapted Vto Venter either slot 17 and lock the mold boardagainst the standard, said device consisting of the two bars pivot'ed onthe interior of the lands-ide and having the free end of one leverextending from the rear end of the lan/iside and adapted to be operatedby the foot; substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
